BUTTER-CUTTER.

Specification of Letters Patent.

Patented Nov. 17, 1908.

Application filed. April 13, 1908. Serial No. 426,706.

To all whom it may concern:

Be it known that I, JENS N. JACOBSEN, a citizen of Germany, residing atEureka, in the county of Humboldt and State of California, have inventednew and useful Improvements in Butter-Cutters, of which the following isa specification.

This invention relates to an improved ma chine for cutting butter, orother material of similar consistency, the object of the invention beingto provide a machine of this character by means of which the entireoperation can be performed in a single continuous movement of thecutting mechanism, in which the force applied to said mechanism isemployed in the most advantageous manner possible, and in which all theparts are readily accessible so that the machine can easily bemaintained perfectly clean.

In the accompanying drawing, Figurel is a side View of the butter cutterin its initial position; Fig. 2 is a similar view showing the parts inthe position when the horizontal cut has just been completed; Fig. 3 isa per spective view of the follower; Fig. 4: is a side view of themachine showing the parts when the vertical cut has just been completed;Fig. 5 is a broken end view of the machine showing the parts in theposition corresponding to Fig. 1; Fig. 6 is an enlarged detail brokenlongitudinal vertical section of the machine; Fig. 7 is a perspectiveView of the block of butter divided into sections.

Referring to the drawing, 1 indicates a metal plate supported upon legs2. Said plate has a transverse upwardly directed rib 3 which has formedon one side thereof semi-circular lugs 4t, around which extend thevertical courses 5 of a zig-zag cutting wire 6, which also extendsaround circular lugs 7 formed on the side of a transverse bar 8, saidwire 6 being secured at its ends to screws 9 on said bar 8. Said bar 8forms the top side of a rectangular frame comprising also posts 10formed integral with said plate 1. The several courses 5 of wire operateas individual wires, and their function is to divide longitudinally andvertically the block of butter into slabs. Secured to screws 11 on theposts 10 is a horizontal'wire 12, which horizontally and longitudinallydivides said slabs in the middle.

Supported upon the plate 1, on opposite sides of the rib 3, are tablesections 13, upon which can slide a block of butter, shown in dottedlines at 14;. To begin the cut, said block is placed upon the rear tablesection in abutment with a follower 15, the latter being secured to afollower plate 16, having sleeves 17 in which are secured guide rods 18,which rod can slide in bearings 19 formed in the plate 1. l

Secured upon the back of the follower plate is a transverse bar 21, theend of which enter cam slots 22 of arms 23 of levers 27 secured upon theends of a shaft 24 extending transversely beneath the plate 1 and havingbearing 26 formed on said plate. Said shaft 24 and both of the levers 27can be moved in unison by means of either or both of two handles 25secured at the ends of the arms 23. The cam slots 22 are eccentric tothe shaft 24 so that by moving said levers 27 forwards, in the directionfrom the position shown in F ig. 1 to that shown in Fig. 2, the bar 21forces the follower 15 to advance the butter over the table sections 13,and thus presses it between the courses 5 of wire, and above and belowthe wire 12, so that, by this horizontal movement, the butter is cutvertically and horizontally into slabs. When said levers arrive at theposition shown in Fig. 2, said wires have passed longitudinally entirelythrough the butter, and are then received in slits or grooves 28 formedin the face of the follower. It is now necessary to divide the slabsthus formed each into two, by a vertical cut through the center. This iseffected by means of a trans verse wire 29 secured at its ends invertical slide rods 30 connected at top and bottom by transverse bars31, and guided vertically in guides 32 also formed integral with theplate. The ends of the lowest transverse bar 31 are extended, as shownat 33, to enter cam slots 34 formed in arms 35 of the cam levers 27.lVhile the horizontal cut was taking place these ends 33 were containedin parts 36 of said slots 34: concentric with the shaft 2-1, so that theframe, consisting of the slide bars 30 and transverse bars 31, wasmaintained in its raised position, the cutting wire 29 being then abovethe level of the top of the butter. But, when the ends of the bar 21arrive at the ends of the eccentric or working portions 22 of theirslots, then the ends 33 of the lowest bar 31 also arrive at the ends ofthe idle portions 36 of the corresponding slots 34 and enter theeccentric working portions thereof. The continued movement of the levers27,.from the position shown in Fig. 2 to that shown in Fig. 4, now, bythe pressure of the upper sides of the slots 34 against, the ends of thelower bar 31, depresses said 31, so that the cutting wire 29 passesvertically through the mass of butter, dividing the slabs into halves.During this movement the follower is maintained stationary by reason ofthe ends ofthe bar 21 being now contained in parts 37 of the slots 22which are concentric with the shaft 24.

The advantages of the invention are the simplicity and cheapness of theconstruction; the convenience of operation, since the entire operationcan be performed in a single continuous movement; the efficiency of themachine, since the force applied to the machine is utilized in the mostadvantageous manner possible; and the fact that all of the parts are soplaced that they can readily be maintained perfectly clean.

A butter cutter comprising a table for I the butter, a leverpivotally connected with said table, a wire for cutting the butter, afollower for pressing the butter against the wire, and a device carriedby said follower and movably engaged by said lever, to move the followerand press the butter against the wire, substantially as described.
